Sorry, I need to be frank. I an get dirreah,but am not sure how far back the meal was that caused it. I typically have undigested looking veggie stool. Anyone know how long it takes for food to come through the tract to show up as dirreah?

It takes approximately 24-72 hours of transit before you eliminate the foods you ingest.SHERRYModerator-Allergies/Asthma and Alzheimer's, Co-moderator-UC~Left sided Uc-'92**Unable to tolerate ALL mesalamines**Colazal(9 daily)/6mp(50mgs)/Bentyl-Prilosec~allergies-Singulair/Zyrtec~Reynauds~OA-Tylonel Arthritis~Scoliosis~Sacroilitis~Dry eye-Restasis~GAD-Klonopin (.25mgs)~Rosacea-Metrogel/Elidel

Food transit times can vary due to a number of reasons. If one has allergic reaction to a particular food, then the food can actually go through a lot faster than 24 hours.

But yes, a food-symptom diary would likely be helpful.

Also, you can get blood testing for IgE, IgA, and IgG antibodies to foods, and this may give you an idea of possible foods to experiment with avoiding for a while to see if it makes a difference.-Razzle

Based on intolerance it can be fast. I have Crohns disease but I have oral allergy syndrome and other food allergies. I am also lactose intolerant. If I have dairy I have delayed reactions to it even with pills to aid digestion in a few hours I have D. With my oral allergy syndrome it isnt abdominal issues it is hives, swelling in my mouth asthma flare etc. With my Crohns though my surgeon told me it can take up to 5 days or sooner based on if I am flaring what the item is etc. I can have flares with my crohns so badly that while eating I have to run and use the restroom. I know food allergies and intolerance can also cause things to have more rapid transit as one of my aunts has similar issues to me with foods (allergy wise) yet hers causes abdominal issues not the same type that I getDx with Crohn's 1987, symptoms as early as 1984.

Yes, the autoimmune panel will probably tell you total IgA, total IgM, total IgG, etc. but won't tell you, for example, if you have IgG antibodies to - for example - corn, or milk, or wheat, or soy, etc... The food-specific antibody tests are usually done by an allergist or naturopathic physician, and usually are most accurate if one is currently eating the foods being tested.-Razzle

I haven't had much luck with food allergy tests. Both my daughter and I have had them and they showed no allergies to food when I know for a fact that we are. I even had some hazelnuts the day before my blood draw and it didn't show up in the bloodwork that I had an allergy - but tell that to my body! lol My daughter's allergist basically told us that these tests are highly unreliable and that we should just listen to our bodies. If you feel a certain food is causing an allergic reaction, avoid that food. That is where a food diary can become your best friend. It should help you pinpoint the foods that are causing you grief.SHERRYModerator-Allergies/Asthma and Alzheimer's, Co-moderator-UC~Left sided Uc-'92**Unable to tolerate ALL mesalamines**Colazal(9 daily)/6mp(50mgs)/Bentyl-Prilosec~allergies-Singulair/Zyrtec~Reynauds~OA-Tylonel Arthritis~Scoliosis~Sacroilitis~Dry eye-Restasis~GAD-Klonopin (.25mgs)~Rosacea-Metrogel/Elidel

You might suspect the magnesium you are taking for the D. 3 x 250 mg a day can be a lot, depending on the dosage in the pills. It would give me D. I can only take 1. 500 x 2 is the dosage for laxative.

As for dairy, suspect lactose first. Most adults, like me, become lactose intolerant as we age. Try lactose-free milk for a week or two, while avoiding all cheese, yogurt, ice cream, etc. There are a couple of other proteins in milk you can try if this does not help. You can get whey protein in grocery stores and try that one as a food challenge if the lactose-free milk is indigestible for you.
